In fact, OpenTBS can merge any OpenDocument files, any OpenXML files, and any XML files compressed in a Zip archive. No extra exe file is required and it makes no temporary files, since all work is done in memory. OpenTBS is based on the TinyButStrong template engine.

KeyValue is a cross-platform library for making C++ objects accessible through LibreOffice Calc, Excel, and other front-ends. This can enhance the experience of spreadsheet users by providing an object model and a handy key-value based interface. Actually, KeyValue does more than just help creating spreadsheet functions. The object model allows end-users to build C++ objects through the front-ends. These objects are stored in a repository for later use at the user's request. Additionally, KeyValue provides a set of services to effectively use these objects. The library is named after one of its main features: the key-value based interface. Parameters are passed to functions (or, more precisely, processors) through key-value pairs, in contrast to the standard positional interfaces of LibreOffice Calc, Excel, C/C++, etc.
